When you lose your car key, there’s the inconvenience of not being able to use your car, plus, you have to deal with an unplanned errand to get a new key made. And there’s the cost of a new key. It’s expensive to have a locksmith create a new key using your car’s ignition, but you don’t have to do it that way. If you know where to look to find the numeric key code for your car, in most cases, you can save yourself the cost of having a locksmith come to you.
Step 1: Check the inside cover of the owner’s manual for the key code for cars built before 1981, or look on the original sales invoice from the dealer.
Step 2: Remove the interior door panel and look for the key code stamped on the lock mechanism.
